OVERVIEW OF GEOLOGIC SETTING OF OURAY Sometimes called the was leader of the Ute Tribe around 1875. The town was first settled by prospectors in 1875 and was incorporated in October of 1876. It was the hub of the Ouray mining district for nearly 100 years. Today the economy of Ouray is based mostly on tourism with mining providing a smaller component in the past 10 years. The town is nestled in a glacial valley in a small mountain park at ~7800 feet at the confluence of the Uncompahgre River and Canyon Creek. Prominent peaks such as Hayden Peak, Gold Hill, Cascade Mountain, and Twin Peaks surround the town. Ouray County was founded in 1883 and is reported to be the first county created following Colorado statehood in 1876 (Dawson, 1954). The population was around 400 citizens, and nearly doubled in 1876 when precious metal deposits were discovered. The town was the hub of mining activity from 1878 to 1986 in the Uncompahgre mining district. Burbank and Luedke (2008) note that this mining in this district produced 2,007,872 ounces of gold, 49,110,490 ounces of silver, 26,609 short tons of copper, 148,253 short tons of lead, and 78,391 short tons of zinc.
